Answer:

The correct answer is "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?"

Explanation:

A compound that prevents the separation of the homologous chromosomes in anaphase I is of great interest since it will cause cell cycle arrest, an effect that is looked in anti-cancer drugs. However, a throughout study of the compound must be done before it could be used for clinical trials. One of the questions that could be answered in this study is: "Is there a pattern to the movement of homologous chromosomes in the presence of this compound?". The answer of this question will let us know if the cells will go to apoptosis, which is what we look for in an anti-cancer drug.

How does hair help prevent diseases?
Maru [420]

Hair plays an important role in our lives. The hair on our head keeps us warm and acts as a cushion for our skull. Hair appearance can also help form our identity and self-image, which makes hair loss very troubling.

Most hair disorders aren’t serious, but they are often considered major cosmetic issues that require treatment. Androgenetic alopecia is the most common form of hair loss, although there are a number of other hair conditions that can affect the scalp and other parts of the body.

what is the difference between the closed conformation and open conformation of chromatin packing? biology
Oduvanchick [21]

The shape of chromatin, which can be either open (euchromatin) or compact (heterochromatin), is dynamically regulated during the phases of the cell cycle is the two types of conformations.

  • The main distinction between conformation and configuration is that whereas the configurations of the same molecule do not easily interconvert, their conformations do.
  • With a predefined location in the nucleus and a certain form, such as metacentric, submetacentric, acrocentric, or telocentric, chromosomes are primarily heterochromatic in this stage.
  • All DNA-mediated processes, including gene regulation, can be significantly impacted by the degree of nucleosomal packaging.
  • While heterochromatin (tight or closed chromatin) is more compact and resistant to factors that need to access the DNA template, euchromatin (loose or open chromatin) structure is permissible for transcription.

In most vertebrate neurons, an action potential arrives at the axon terminal and causes the release of chemical messenger molecu
erik [133]

The correct answer is option d, that is, neurotransmitters.  

A neurotransmitter refers to a chemical component, which is discharged at the terminal of a nerve fiber by the introduction of a nerve impulse, and by diffusing across the junction or synapse. It helps in the transfer of the impulse to another muscle fiber, nerve fiber, or some other composition. Acetylcholine is a kind of neurotransmitter, that is, used by neurons in the CNS and the PNS in the control of activities ranging from heart rate and muscle contraction to digestion and memory.
